GPSAltitude not being read from videos

[johnbeardy]

I have mp4 videos tagged with GPS data in Adobe Bridge, and I can see GPSAltitude is listed with other GPS attributes in the Advanced tab, but it doesn't seem to be reliably extracted to JSON.

When I specify JSON output and target Exif tags, GPSAltitude is not returned.

Code Select Expand

-XMP-exif:all  -j  > "C:\Users\john\Documents\jb Metadata xmp extract.txt" -n

"GPSLatitude": 54.4299966666667,
  "GPSLongitude": -3.09098833333333,
  "GPSProcessingMethod": "MANUAL",
  "GPSAltitudeRef": 0

But it's present with XMP output

-XMP-exif:all  -X  > "C:\Users\john\Documents\jb Metadata xmp extract.txt" -n

<XMP-exif:GPSAltitude>150.00 m</XMP-exif:GPSAltitude>
<XMP-exif:GPSLatitude>54.4299966666667</XMP-exif:GPSLatitude>
<XMP-exif:GPSLongitude>-3.09098833333333</XMP-exif:GPSLongitude>
<XMP-exif:GPSProcessingMethod>MANUAL</XMP-exif:GPSProcessingMethod>
<XMP-exif:GPSAltitudeRef>0</XMP-exif:GPSAltitudeRef>

When I specify JSON and extract all tags, GPSAltitude is returned as expected. Add ideas, Phil?
